So I was too busy and skipped the book part. My husband and i concentrated on the practice questions. He used the unpaid ones he could find on youtube. Look for the updated ones. I started with the paid version but i got more confused because there were too many questions. Anyways I moved to the unpaid versions. We would look up whatever we could find on youtube and we practiced till we scored over 95 percent on most of them.
Was the test hard. No. It was very basic and we were done in five minutes. I encourage you to read the book if you can though
